Outlook Web Access to Microsoft Exchange Server

Note: Exchange 2000 is past its natural support cycle, with limited support available. This content will remain for reference use however some of the content linked below many no longer be available. 

Outlook Web Access (OWA) allows any client with a compatible browser to access Exchange Server folders.

For Exchange 2000, you create applications using web forms. No conversion tool is available to turn Outlook forms into Exchange 2000 OWA forms. For resources and tools, see Microsoft Exchange Server Development Technologies. With Outlook 2002 and Exchange 2000, you can connect using OWA and Outlook 2002's support for HTTP mail servers (at least those that use WebDAV). The correct URL would be http://servername.domain.com/exchange/mailboxname.

There are issues using OWA on Vista because the dhtml text editor control used by OWA is not supported in Vista. The Exchange administrator should have installed the security patch for this on the Exchange server months ago, but many have not. The patch will fix this and a similar issue that affects Windows XP users who've installed the security patch described in MS06-013. The hotfix installs a new editor for Internet Explorer which uses an iframe instead of an ActiveX control.

If you are an end-user, contact your administrator. If you are an administrator, see the following links for more information and the hotfix. 

You receive an error message when you try to perform any editing tasks, or you must click to enable the compose frame in Outlook Web Access http://support.microsoft.com/default.aspx/kb/911829.

    The following tools are generic OWA tools. While many will work with Exchange 2000, some require newer versions of Exchange server.

    Notes

    		 While OWA for Exchange 2000 will resolve addresses against both the user's default Contacts folder and the Global Address List, clicking the To button on a new message displays only the address book, not the Contacts folder. Tools like the Plus Pack for Outlook Web Access 2000 can add addressing from the user's Contacts folder. For public contacts folders, users can open a contact and copy and paste the address into a message. Also see Resolving Contact Names to Addresses Through OWA.
